This is an old map that I started making a long time ago but never finished. Basically, this is a multiplayer combat game that acts a lot like FortNite, but uses cardboard for everything.

There are 6 different types of weapons: pistol, assault rifle, machine gun, shotgun, sniper, and bazooka. And, there are 5 colors to determine ranking: gray, green, blue, purple, and gold. Gold is the best. The pistol, rifle, and machine gun use light ammo, the shotgun and sniper use heavy ammo, and the bazooka uses rockets. Right click to shoot, and sneak to reload and put ammo items in your corresponding ammo magazine.

For box building, you can build a ramp, floor, or wall. First, make sure you have at least 1 cardboard and 1 tape, then click in an open enough space. Sneak to build closer to you. Use the box destroyer axe to break a piece of cardboard and break the whole 2x2 area (only works in survival mode).

For the sniper, sneak to zoom. For the bazooka, the rocket will explode when shot and break cardboard.

Just play around with it and discover what you can by experimenting. I put a lot of work into this, but a lot more work would be needed to fully polish this off.
